Bureaucrats or Politicians?

Policies are typically chosen by politicians and bureaucrats. This paper investigates the criteria that should lead a society to allocate policy tasks to elected policymakers (politicians) or non elected bureaucrats. Politicians tend to be preferable for tasks that have the following features: they do not involve too much
specific technical ability relative to effort; there is uncertainty ex ante about ex post preferences of the public and flexibility is valuable; time inconsistency is not an issue; small but powerful vested interests do not have large stakes in the policy outcome; effective decisions over policies require taking into account policy
complementarities and compensating the losers; the policies imply redistributive conflicts among large groups of voters. The reverse apply to the attribution of prerogatives to bureaucrats.
